GASOLINE-STORAGE-TANK FITTING.

Application filed February 5, 1927. `'Serial No. 166,263.

My invention relates to a fitting for storage tanks such as are employedfor holding gasoline, and more particularly the inven t1' on relates toa fitting for sub-surface gasoline tanks. The usual arrangement andequipment of a subsurface gasoline tank requires the digging up of theground or the floor surface of the garage When installed in a garage,Whenever the foot valve, for eX- ample, or discharge pipe becomesdisarranged or inoperative.

The general object of my invention is to provide a fitting for asub-surface gasoline tank which when coordinated With a tank and itsappurtenances ivill make it possible to remove the discharge pipeleading from the tank and carrying the usual footvalve so that thedigging up of the ground or the disturbance of the tank or itssurroundings Will not be necessary Whenever it is desired to gain accessto the discharge pipe or foot valve for repair or otherwise.

The nature of my invention and its distinguishing features andadvantages will clearly appear as the description proceeds.

Reference is to be had to the acco1npanying drawings forming a. part ofthis specication, it being understood that the dravvings are merelyillustrative of one example of the invention.

Figure 1 is a vertical section through kthe upper portion of asub-surface gasoline tank equipped With my invention.

Figures 2 and 3 are horizontal sections taken respectively on the lines2 2 and 3-3 in Figure 1.

Figure 4 is a perspective View of the rcmovable plug carrying thedischarge pipe from the tank, said pipe having the usual foot valve.

In the illustrated example of my invention, the numeral indicates theupper portion of a sub-surface gasoline tank shown as covered byconcrete 11 and 12 indicates the concrete floor a distance above thetank 10. The tank 10 is formed in the top thereof With an opening 13 andprovided at said opening With a flanged, internally threaded collar 14.A fitting 15 has threaded engagement with the collar 14 and has anexternal flange 16 on which rests a cover pipe section 17 extendingthrough the floor 12 as Well as through the earth intervening betweenthe tank 10 and said floor. The numeral 18 indicates a disch-erge pipefor the outflow tank 10 is equipped as usual With a foot valve 21. Inorder to permit the ready removal of the pipe 2O with the foot valve 21Without disturbing the floor 12, the tank v10 or the intervening earth,I provide the following arrangement: The fitting 15 is formed with aninternal thread 22 and engaging said thread is a screvv plug 23. Theplug 23 is formed at the bottom With an internally threaded recess 24and in register -ivith said recess is la central outlet opening 25 sothat the gasoline may pass from the discharge pipe through the plug23vand thus to the outlet pipe 18.l

The opening` is squared or otherwise non-circular in form to receive acorrespondingly formed Wrench, `not shown, so that the Wrench wheninserted through the cover pipe section 17 may be caused to unscrevv theplug 23 for lifting said plug and With it the pipe 20 and its foot valve21. For lifting plug v23 and pipe 20 I may, as shown, form the plug 23with an interior crossbar 26 to be engaged by a hooked tool of anycharacter, said tool not being shown.

Above the bushing or plug 23 is a plug 27, advantageouslyascrevv plugWhich is spaced above the bushing 23 sufficiently to form an interveningchamber for the reception of the oil and to maintain a supply for theoutlet pipe 18. The plug 27 is formed With a non-circular depression 28to receive a wrench and with a cross-bar 29 to be engaged by a hookedtool. cover pipe section 17 or cover of the fitting 15 is closed by anysuitable plug or other closure 30. Below the top of the covery pipesection 17 is a spider or grid 31 to center the Wrench and lifting tool.

I would state furthermore that While the illustrated example constitutesay practical embodiment of my invention, I do not limit myself strictlyto theexact details herein illustrated, since, manifestly, the same canbe considerably varied Without departure from the spirit of theinvention, as defined in the appended claims.

lWhat I claim is:

Tl, An attachment of the character de The top of the a Voi.said counterbore and sustained by scribed for underground liquid tanks, comprising alitting adapted to be secured to a tank and internally screw threadedintermediate ot its ends, an externally threaded plug engaging saidinternal thread and formed with a vertical opening for the outflow ofthe liquid contents ot the tank, said plug having at the under side aninternally threaded counter bore and a discharge pipe engaging thethreads otl said counter bore and sustained by said plug.

2. An attachment of the character descrihed for underground liquidtanks, comprising a litt-ing adapted to be secured to a tank and havingintermediate. of its ends an internal thread, a screw plug engaging saidinternal thread and Jformed with a vert-ical opening tor theoutow ott'the liquid ecntents of the tank, said plug having at the under side aninternally threaded counter bore anda discharge pipe engaging thethreads said pluggthe opening in said Aplug' being noncircular' toaccommodate a wrench and there being a member on said plug at theinterior ofthe opening to yreceive a hook for lifting the plug and thedepending pipeV through said itting.

i 3. An attachment of the character described ior underground liquidtanks, comH prising a fitting adapted to be secured to a tank and havingan internal screw thread intermediate ot its ends,.a screw plug engagingsaid internal thread and :formed with a vertical polygonalopening forthe outflow of the liquid contents of the tank, said plug having attheunder side an internally threaded counter bore, a discharge pipe engaging the threads of said counter bore and sustained by said plug,` anda removable closure tor the upper end of the fitting.

4. In an attachment for underground liquid tanks, a fitting internallyscrew threaded intermediate of its ends and having its upper endinternally screw threaded and its lygonal opening lower end externallyscrew threaded to permit it to be secured to a tank, a screw threadedplug engaging the intermediate screw threads ot the titting and having apo to receive a wrench and with a member adapted to receive a hookedtool, a discharge pipe secured to said plug, a screw threaded plug inthe upper' end of the fitting and having a polygonal opening to receivea wrench and a member adapted t0 be engaged by a hooked tool, adischarge pipe connected with the itting between the plugs and a ventpipe connectedwith the fitting below the irst plug.

5. An attachment tor underground liquid tanks, comprising a littinginternally screw threaded intermediate of its ends and having its upperend internally screw threaded and its lower end externally screwthreaded, the fitting being provided adjacent its upper `end with anexterna-l annularllange, a screw threaded plug engaging the intermediatescrew threads oi2 the fitting and having a po lygonalepening and amember adapted to be engaged by a hookto litt the plug, the plug havinga screw threaded recess on its under side, a discharge pipe screwinginto said recess,` a screw threaded plug in the upper end ot thefitting, and a pipe `section resting on the 'flange ot the fitting andprovided with a closure at its upper end.

(i. An attachment for underground liquid tanks, comprising a fittingadapted to be secured to a tank and having-an annular enter nal shouldernear its upper end, removable spaced plugs in the litting, the lowerplug having an opening therein and Vto which a discharge pipe is adaptedto be secured, the

itting being provided with an outlet between the plugs and with an airventbelow the apertured plug, and a pipe section on the iange of thefitting and provided at its outer end with a closure.
